An expensive fifth-generation stealth fighter program that cost the United States $66.7 billion to complete, the first F-22 aircrafts were plagued with complicated issues regarding the pilot's oxygen systems, which caused hypoxia-like symptoms responsible for the crash and death of pilot Capt. Jeff Haney in November 2010. An Air Force official made clear that the latest incident is unrelated to defective oxygen systems.

Air Force officials also confirm that the fighter pilot is in "good shape" and has been cooperating with investigators to determine the cause of the crash. An official says, "Initial indications are, from talking to the pilot and from analyzing initial evidence... [that] it doesn't look like it was related to any physiological problems."

The single most expensive fighter in the sky, the ultra-manueverable F-22 Raptor jet is armed with two Pratt & Whitney F119-PW-100 jet engines capable of pitch axis and thrust vectoring. Each jet engine produces approximately 35,000 pounds of thrust. Detailed specs on this military aircraft are classified.
